This week's event is an Olympic qualifier for American Big Air athletes, as the sport will make it's debut at the Pyeongchang Games in February. In order to qualify for the Olympic team via the objective criteria, athletes will need to have at least one podium finish against the competition field in the selection events, such as this week's competition at Copper. If three or fewer athletes meet that criteria, those athletes will automatically be named to the Olympic team. If four or more athletes have at least one podium finish, then those athletes will be assigned ranking points based on their two best results from the selection events.
